Mouting bracket with relays.

In place

 
 

Mounting bracket was manufactured from a piece of aluminum. It is important to follow exact recommendations published in "Mounting relay instructions" on www.somis.org. Otherwise, you will get a "loud" QSK. It won't be pleasant.

It is recommended to test the vacuum relay before it gets attached to the mounting bracket.
I installed MATSUSHITA reed relay next to the vacuum relay using red silicone rubber by General Electric.
